The investigation was launched after criticism from FUR claimed in-date products the organization donated to the shelter were being sent away.
Fairburn said he managed to clear some of the air with FUR during the Friday meeting.
"I think we are working positively together for the good of all animals now," he said.
Friends Fur Change released a statement on Friday confirming they are happy with the direction the city was moving in regards to the shelter.
"Friends Fur Change was extremely pleased with the city manager's decision to immediately begin utilizing funds to spay/neuter and ready our small friends at the shelter for adoption. We are also very happy about his decision to amend the shelter's budget with funds for food for the animals. This will allow us to concentrate our efforts on community awareness and advertising these precious dogs and cats to their potential forever homes. We look forward to working together with the city to build a shelter program that makes a real difference in the lives of our pet population and makes every citizen of Chickasha proud."
In a previous Express-Star story, Fairburn said excess food from the shelter used to be given to a local farmer. He said the recipient worked with the city to find homes for feral animals, which is why he was given the resources.
"This arrangement was going on for years, well before my time," he said.
FUR complained employees at the animal shelter had become difficult to work with this week, and that they wouldn't let volunteers enter the shelter to work with the animals.
Fairburn said although not fully resolved, he is working on mediating the problem.
"We want to make sure they are treated nicely, just like an employee or citizen would want to be treated," he said.
